According to the FBI, over 1.5 million background checks on customers were requested by gun dealers to the National Instant Criminal Background Check System in December. Nearly 500,000 of those were in the six days before Christmas.

It was the highest number ever in a single month, surpassing the previous record set in November.

On Dec 23 alone there were 102,222 background checks, making it the second busiest single day for buying guns in history.

The actual number of guns bought may have been even higher if individual customers took home more than one each.
